Application filed September 9, 1914. Serial No. 860,845.

To aZ? whom it may concern:

uvn that l. l-lnnnox B. La rnxx. Ann of the United States, and residingat her. fork. in the county of New York and t ate oi Xew York, haveinvented certain new and useful Improvements in Interual-CoinbustiouEngines, of which the following is a i-specilication. such as willenable those skilled in the art to which it appertiiins to make and usethe same.

This inventioirrclatcs to explosion or intornal ii-onllur--xtionengines. and particularly to engines oi this class. oi the sleeve valvetype. and the object thereof is to improve the construction and methodof assembling the separate parts of an engine of this class so tofacilitate the machining or finishing of the valre ca and reduce thecost of such work; and an this and other objects in vievr the inventionconsists in the improvements in engines oi this class hereinafterdescribed and claimed.

Tl 1e invention. is fully disclosed in the following specification, of vaich the accompanying; mlravcini: Forms a part. in which the separateparts of my improvement are desig nated by sun bl: reference charactersin each of the Men's, and in Which:-

l ig'ure 1 a central vertical transverse section. through one unit of aninternal conibustion engine involving a plurality of units and madeaccoriiliug to my invention; Fig. 2 a view similar to Fig. l, butshowing only one-half of the unit. and showing a inoclifiaition. andFig. 3 a view similar to Fig. 2, butshowing another modification.

In the practice of my invention, as shown in Fig. 1. the cylinder a. andits outer casing or acket (1 are formed integrally and con nected at thetop by a horizontal plate memher a in which are formed ports or passagesa and a.

The explosion. head i'- of the cylinder a is formed arately and containan annular valve casing Z and inlet and exhaust 1nani folds 7) and 71andv the explosion chamber 5 The cylinder (4 has a. reduced. neck a,which communicates with the explosion chamber 6 and the walls '1 of theexplosion chamber 71" are cylindrical in form in horizontal section. andsaid explosion chamber is of much. less dimensions transversely, thanthe cylinder (1.. The inlet and exhaust mani folds b and b are placed.in communication \Yl'tll 'lilie explosion chamber 5 by radial ports orpassages F2 and 3 and these or passages are controlled by the sleevevalve 0 mounted in the-valve casing 6 or in an annular chamber F).formed therein. The valve chan'iber 7) opens downwardly through theexplosion head 6, and said valve chamber is comparatively large intransverse section and provided vrith inner and outer linings c and cbetween which the valve 0 is movable in the usual manner, By this methodof forming explosion head 7) the forming and finishing of said head. orthe separate parts thereof, is facilitated, and the valve chamber thewalls of which are cast integrally with the explosion head, may bemachined or finished at a much less ex'glense than is ordinarilynecessary in engines of this class, it being understood that the liningsc and c of the valve chamber, and between which the valve movable, maybe machined or finished "much more easily and expeditiously than theinner Walls of the valve chamber 5*.

The valve chamber Z), in this form of construction, is entirelyinclosecl both inside and outside thereof, by water chambers or passagesr? and (Z and the outer chamber or passage (Z incloses the inlet andexhaust manifolds .71 and b, and said Water chambers or passages d anda? are provided in the bottom thereof With ports (3?- and 03, whichregister with the ports and a, and in this way the water. chambers orpassages (Z and (IZ in the explosion head I) are placed in com--munication with the main water chamber or passage (1 around the cylinderThe cylinder a contains the usual. piston c. and when the engine use,Water from the radiator enters the ciainbcr or m at or near the bottom'tl'icrco'l in the usual. manner. and passes upwardly ljherethrou h andinto the lvilllfil' chambers or passages and [2 from vvnich it passesback to the raoiator in the usual manner. and in this way there is acontinuoi'ls circulation of water around the cylinder (1, through theplosion head around the inlet and exhau. t manifold F9 and hi andupwardly on both the inner outer oi the valve ca in; b

in the top or the explosion hea. I a countersunk chamber or recess f,between the bottom oil Whicl'i and the explosion charm l bottom Walls ofthe valve easing her or the walls thereof, is an annular space f incommunication with the water chamber or passage (Z and (Z and thecounter-sunk chamber or recess f is placed in communication with theexplosion chamber 5' by a threaded bore f into which, in practice, thespark plug screwed.

F 1,111 an explosion engine,

heconstruction shown in Fig. :2 is exactly the same as thatshou'nin'Fig. 1, except that the explosion chamber 72 is larger, and isnot inclosed by a water chamber or passage, the water chamber or passage(Z extending downwardly only to the top, or top wall 6" of the explosionchamber, and the side walls of the explosion chamber are formed by theIn the construction shown in Fig. 3, the outer Walls of the valve casingZ) and the inlet andeXhaust-manifolds have no water jacket, but'theinner water chamber or passage dis employed the same as in Fig. 1, andthls water chamber or passage is placed in communication with the waterchamber or passage a, which inc-loses the cylinder at by means of theports or passages a and 03 as in frig. 1.

i From the foregoing description, it will be seen that the main-featuresof my improve ment, and which characterizes all of the forms shown,consist in forming the valve chamber entirely in the detachable head 6of the engine, and from the fact that the valve chamber opens downwardlythrough said head, and by detaching the head 6, all the parts thereof,including the valve and valve chamber may be readily cleaned, orrepaired, whenever necessary, and a new "valve and new lining for thevalve chamber may also be substituted for the old one at any time.

In the accompanying drawing no means for operating the valve are shown,but it will be understood that any preferred construction or mechanismfor this purpose may be ,emlployed.

aving fully described my invention, what I claim, and desired to secureby Letters Patent is 1 a cylinder provided with a water jacket, and adetachable explosion head mounted on said cylinder and jacket, andprovided with a water chamber or chambers in communication with thewater chamber between the jacket and the cylinder, said explosion headbeing also pro vided with an annular valve casing formed entirely insaid head and in which is mount eda sleeve valve which controls theinlet and exhaust ports or passages.
